This is the C-35 Mini High Frequency Electronic Speed Control w/BEC.
For medium sized performance aircraft with 400, 500 or 600-size
Brushed Motors requiring 35A or less.

FEATURES

Compact size to minimize weight and simplify installation
Programmable battery types
Automatic temperature protection reduces max throttle to 70% when max
temperature is reached
"Safe-Start" system prevents accidental motor starts by disabling the
motor circuitry until the throttle stick is moved to full throttle,
then to the OFF position
Factory installed radio, motor and battery connectors
Fully proportional forward with brake
Battery Eliminator Circuitry provides sufficient power for the
receiver and three standard servos. The motor battery powers the
receiver and servos. When voltage is reduced to the appropriate
voltage, the Low Voltage cut-off circuitry stops the motor while
continuing to supply power to the receiver and servos.
Solid-state current overload limiter
Built-in thermal protection drops throttle to 70% if
transistors overheat
Reverse-polarity protection
High Frequency to optimize battery run-time and cool operation.
ON/OFF radio switch and set-up LED light
180 day limited warranty
